<DL>
<DD>Produces a branched logger, which can be used to write messages that are
 logically grouped together underneath the current logger. The details of
 how/if the resulting messages are displayed is implementation-dependent.
 
 <p>
 The log message supplied when branching serves two purposes. First, the
 message should be considered a heading for all the child messages below it.
 Second, the <code>type</code> of the message provides a hint as to the
 importance of the children below it. As an optimization, an implementation
 could return a "no-op" logger if messages of the specified type weren't
 being logged, which the implication being that all nested log messages were
 no more important than the level of their branch parent.
 </p>
 
 <p>
 As an example of how hierarchical logging can be used, a branched logger in
 a GUI could write log message as child items of a parent node in a tree
 control. If logging to streams, such as a text console, the branched logger
 could prefix each entry with a unique string and indent its text so that it
 could be sorted later to reconstruct a proper hierarchy.
